Now that both system's are built on ASP.NET MVC, does anyone have any experience dealing with both? Looking to set up a small business site for a friend, that will eventually have an online store. I've read a lot of posts, but nothing recent ( since Umbraco 5 was released ). If you've had experience, just looking for pros and cons. Anything related to commerce functionality would be helpful as well. Thank you.
Orchard has been built from ground-up around ASP.NET MVC 3. I personally prefer that one, as it's well designed, very active and backed by Microsoft. And, of course, totally free.
If you are looking for e-commerce solution - there is a new, very promising module called WebShop, along with a full tutorial.
